alpha functions render the meshes twice

[werner.poetzelberger]

Hello,

as soon as activating one of the alpha functions, the amount of polzgons double.

Where is this coming from, and is this avoidable?

thx.

Hi Werner,

This is expected behavior. Alpha blend enables forward pass for the selected material, which means that each additional light source, environment probe and other passes (like refraction, reflection, ambient, emission and etc) will cause the geometry to render one more time.
